Try to break your problem down into small pieces, and then take on those pieces one at a time.
Can you get your robot to display a single color? Just try to get it displaying red.
Separately, can you get your robot to say a single color? Just try to get it to say "red".
When you have those steps working, then keep going from there. If you get stuck, post the code you have so far and we'll go from there. Good luck, sounds like a fun project!
